We took a look at this – one potential drawback is the there’s no user interaction meaning the updates applied would be what’s presented in the Offline Servicing view. That’s the default view – filtered for that architecture.

Could this not be linked to an ADR and Software Updates? We use a test ADR and a Production ADR, the production ADR is a bit behind our test so we can have time to exclude anything. This would be great if we could say "Apply Production ADR to OS Image using offline servicing"

Yes, anything is better then Nothing, but if I remember right offline servicing view is shower very limited number of updates. It would be good to at least allow all Critical and Security updates. But either way, Any amount of automation is good.
